  2. 6. How ISM properties drive Lyman Continuum Escape

    Author : Johannes Puschnig; Matthew Hayes; Göran Östlin; Rahman Amanullah; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Astrophysics; Cosmology; Extragalactics; Reionization; Lyman Continuum; Interstellar Medium; ISM; Tololo 1247-232; Astronomy; astronomi;

    Abstract : The thesis introduces physical processes that are at work in astrophysical plasmas and reviews the current state of research related to the emission of ionizing photons, i.e. Lyman continuum (LyC). Star forming galaxies and active galactic nuclei are discussed as sources of LyC. READ MORE

  4. 7. Dissolved organic matter in lakes : Chemical diversity and continuum of reactivity

    Author : Alina Mostovaya; Lars Tranvik; Colin Stedmon; Uppsala universitet; []
    Keywords : dissolved organic matter; DOM; dissolved organic carbon; DOC; PARAFAC; reactivity continuum model; ultrahigh resolution mass spectrometry; FT-ICR-MS; organic matter characterization; decomposition kinetics; baseline metabolism; Biologi med inriktning mot limnologi; Biology with specialization in Limnology;

    Abstract : Dissolved organic matter (DOM) is the largest pool of organic carbon in aquatic systems and an important component of the global carbon cycle. Large amounts of DOM are decomposed within lakes, resulting in fluxes of CO2 and CH4 to the atmosphere. READ MORE

  5. 8. Continuum modeling of the mechanical properties of paperboard

    Author : Eric Borgqvist; Hållfasthetslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; director vectors; polyconvexity; plastic spin; creasing; anisotropy; fiberous materials; Continuum Modeling; Paperboard;

    Abstract : Continuum based elasto-plastic models for paperboard have been established in the work herein. The thesis begins with an introductory section that describes some of the background of the problem and gives some more motivation for the modeling choices made in the appended papers. READ MORE

  6. 9. Continuum modelling of particle flows in high shear granulation

    Author : Per Abrahamsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; parameter study; High shear granulation; continuum modelling; resolution dependence; granular flow; compartment model; kinetic theory of granular flow;

    Abstract : High shear granulation is an important process in the pharmaceutical industry. The aim of the process is to produce granules with specific properties, like size and hardness, from powder mixtures. The properties of the granules are determined by the flow field in the mixer.
